WATER-HEATING GAS PLATE.

Application filed September 22, 1923. Serial No. 664,161.

To all whom it may concern:

Be it known that I, JOHN A. BERo UIsT, a citizen of the United States,residing at Duluth in the county of St. Louis and State 5 of Minnesota,have invented certain new and useful Improvements in Water-Heating GasPlates, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to water heating gas plates and has for itsprincipal object to produce a simple and practical means for heating thewater simultaneously with the use of a gas plate.

Other objects and advantages of the invention will appear in the furtherdescription thereof.

Referring to the accompanying drawing forming part of this applicationand in which like reference characters indicate like parts:

Figure 1 is a top plan view, partly broken away, showing the interiorconstruction thereof; and

Figure 2 is a vertical section taken on the line 2-2, Figure 1.

1 represents the body portion of a double hole gas plate, which in planview is preferably substantially rectangular in shape and hollow, itbeing made of suitable cast metal. Upon the upper surface of the plateis any desired arrangement of supporting webs 2 upon which receptaclesused on the gas plate may rest, as is customary in such devices.

The holes through the gas plate are indicated at 3 and i, beneath whichany suitable form of burner, as indicated at 5, is installed, and thecir umferential walls of these holes I prefer to construct somewhattapered, as clearly seen in Figure 2 of the drawings, the upper surfaceof the plate being inclined downwardly as at 6 towards the edges of thehole, while the under surface of the plate is arcuate in shape as at 7,the latter being for the purpose of pre senting as great a surface aspossible to the flames of the burner, as well as reinforcing the edgesof the hole against sudden contraction and expansion.

The interior of the plate I prefer to divide as by the vertical walls 8and 9 forming a tortuous course for the water as it circulates throughthe plate, the entrance of the water into the plate occuring at asuitable orifice indicated at 10, while the discharge orifice isindicated at 11. By this means the water entering the orifice 10 isobliged to pass around to the right of the hole 4 as viewed from aboveand thence to the left partially around the hole 3 before it reaches theexit orifice 11. About the orifice 11 I propose to form the chamber 12by the arcuately shaped upstanding wall 13 which does not quite reachthe upperinner surface of the plate; this being for the pur- I pose ofpreventing cold water being discharged through the exit orifice andnecessitating the water rising above and over the wall 13 before it canbe ejected.

Spanning the hole 4 I have shown a hollow spider 14: which may beresorted to as an additional means of quickly heating the water, andthis spider or additional heating chamber may be of any shape desired.

It is obvious that such a plate may be connected up to any form ofstorage tank or other device in which heated water is used and in thismanner provide an exceedingly simple means for constantly supplying warmwater during the use of a gas plate.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. The combination with a gas plate of the character described havingtwo spaced burner holes therein, of a water chamber within the plateabout the holes, a vertical division wall within the chamber extendinghorizontally between the holes, a second division wall extending fromthe center of the last mentioned division wall to one side of the plate,and water entranceand discharge openings through the outer wall of theplate one upon either side of the last metioned division wall,substantially as and for the purpose described.

2. The combination with an organization as set forth in claim 1, of anupstanding protecting wall about the discharge opening to cause only thewarmer water to pass therethrough.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses. JOHN ALBIN BERGQUIST. Witnesses:
